What is gravity and who came up with the idea?
Gravity is a force that exists, it is not like someone thought of it and then simply things started to fall down. It is very likely mankind discovered that things fell down after being thrown up at early stages of their development. As for any scientific theory of gravity, describing in mathematical terms what it does, this is usually credited to Isaac Newton who published his equation in 1687.
Why is Scientist Dorothy hill famous?
Because he was very intelligent
Who made up gravity?
Gravity was not "made up" by any individual, but was rather observed and described by numerous scientists throughout history. Sir Isaac Newton is known for his law of universal gravitation, which explains the force of gravity between all objects with mass.
Why is careful obersavation important to being a scientist?
A scientist may create an hypothesis on the basis of their observations. If their observations are carelessly made or recorded then any hypotheses they offer will be inaccurate reflections of nature. A scientist may alternatively collect observations to test an hypothesis. If these observations are carelessly made or recorded then the conclusions that the scientist makes about the hypothesis could very well be incorrect. At the very least the conclusions they draw would not be based on sound evidence (because the observations are unsound).
The fact that the sun exerts a force on you even though it is very far away is a consequence of the universal law?
of gravitation, as formulated by Sir Isaac Newton. The law states that every mass attracts every other mass in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. This means that even though the sun is far away, its massive size still exerts a gravitational pull on objects, such as us on Earth.
